9 Claims.

This invention relates to the class of surgical instruments, and more particularly to a holder for immobilizing a needle used in intravenous injections.

In the transmission of fluid either into or from the human body, such as the extraction of plasma 01' blood from the body or the transmission of fluid for feeding purposes thereinto, it has been found that the usual method of keeping the intravenous needle in place requires bandages, gauze, tape, etc. which require constant attention by the attending physician or nurse so as to assure functioning of the needle while the injection is being administered. This causes inconvenience, discomfort for the patient, and requires the valuable time for the medical professional, all of which it is an object of the present invention to eliminate.

Another object of this invention is to provide an intravenous needle holder in which an intravenous needle may be firmly and securely held in a selectively adjusted position.

Yet another object of the invention is to provide an extremely simple means for adjusting an intravenous needle after it has been secured to one of the movable parts of the intravenous needle immobilizer.

Still other objects of the invention reside in the provision of an intravenous needle holder which is strong, durable, eificient in operation, relatively simple in manufacture and construction, easy to adjust and operate, and comparatively inexpensive.

These, together with the various ancillary objects of the invention which will become apparent as the following description proceeds, are attained by this intravenous needle immobilizer, a preferred embodiment of which has been illustrated, by way of example only, in the accompanying drawings, wherein:

Figure 1 is a top plan view of the device comprising the present invention;

Figure 2 is a front elevational view of the intravenous needle immobilizer;

Figure 3 is a horizontal sectional view, showing the operative structure of the intravenous needle holder in greatest detail;

Figure e is a top plan view of the intravenous needle holder showing it in position on a limb of a patient, with an intravenous needle in suitable emplacement; and

Figure 5 is an exploded view in an enlarged scale and in perspective, showing the relationship of the various elements comprising the ad- Justable parts of the present invention.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, to indicates a base plate on which the various elements incorporated in the present invention are suitably attached. The base plate i8 is curved to approximate the shape of a limb upon which it is to be emplaced and has a slot i2 into which one end of a belt I4 is inserted for subsequent stitching to form a connecting loop as at It. The other end of the belt I4 is provided with an adjustable buckle formed in several sections as is illustrated and indicated generally by reference numeral [8 which is adapted to engage over a suitable hook or catch 20 secured to the plate l0.

Riveted, welded or elsewise secured to the base plate In is a bottom radius guide 22. By means of spacers. 24 and 26, an upper radius guide 28 is spaced from the lower radius guide 22. By screws 36 and 32, the upper radius guide 28 and lower radius guide 22 may be rigidly secured together forming an opening E i therebetween. The radius guides are arcuate in shape as can best be seen in Figures 1, 3 and 4.

On either side of the radius guides 22 and 28 are positioned spacers 3t and 38 which have apertures as at 40 therein in alignment with the opening 34 between the upper and lower radius guides. These spacers 36 and 38 are arcuate in shape and are of the same radius of curvature as the guides so as to suitably engage them. A slide holder 42, as best shown in Figures 3 and 5, is provided with an aperture as at 64 therethrough in alignment with the apertures 49 and opening 34. The slide holder is provided with upper and lower walls each having an end having a similar and almost equivalent radius of curvature as the guides and spacers so as to suitably engage the spacer 36. The side walls of the slide holder 5.2 are provided with projections 46 and 48 which are adapted to be inserted withinthe opening 40 in the spacer 36 and extend partially into the opening 34 between the radius guides.

Within the slide holder is slidably emplaced a slide 56 having a notch 52 in one side wall together with a slot 54 in one end wall. A pair of holes 56 and 58 are vertically formed in the slide 50 in communication with the slot 54 for a purpose to be henceforth explained. The notch 52 is of such shape as to leave a wall 58 which is formed at an angle to the end and side walls of the slide 50.

By means of a pair of pins 60 and 62 a pair of spreader members 64 and 66 are secured at spreader members.

one end in a pivotal manner within the slot 54 in the slide 50. The spreader members 64 and B6 are provided with cam surfaces 68 and it which are adapted to abut against the side walls 46 and 48 of the slide holder :82 and to abut against suitable side walls of the spacer 38. The spreader members are provided with apertures 12 and 14 therethrough together with another set of apertures 16 and 18. Additionally, threaded holes 80 and 82 are formed in the end of the spreader members opposed to the end having the cam surfaces $8 and 7B thereon. A spring 84 of suitable configuration is, emplaced With its ends inserted in the apertures 72 and It in the This spring. is of such shape as to urge the spreader members to part and subsequently urges the team surfaces against their engaging surfaces so as to urge the slide out of the slide holder. By means of screws 86 and 88 a pair of opposed jaw members 98 having upwardly extending legs 92 and 9d are provided and pivotally secured to the spreader members. A pair of rubber sleeves 35; are positioned over each of, the leg members 92-. and 9 3. A spring 98 is secured to, each of the legs 52 and the rubber sleeve 96 is positioned over it to hold it in. place. The other end of the spring 98 is passed. through the apertures 1-6, '18.

The slide holder 42 is provided with .a threaded aperture Hill. which communicates with the aperture 44 therein. A threaded locking pin r82 having an enlarged knurled head we is threaded into; thea-perture 468 and has its conical pointed end I06 engaging the cam surface 58 on the slide.

The. device is operated as follows:

Since the action of the spring 86 will hold the entire assembly of movable parts in place as desired on the radius guides, the assembly may beslid as desired within the opening 34. Thusly, the intravenous needle holder may be given .a .rotative movement about the base plate it. Since the spring 8 additionally urges .thespreader members 5% and it outward of the spacing member 38., this in turn causes the slide 50 to pass through the aperture ii; in the slide holder tov such position as finally limited by the adjusting screw [$32. This limits the position of the slide. A suitable syringe or intravenous needle asshown Figure 4, may be inserted between the jaw members 539 as desired, with the rubber sleeved legs conforming to the configurationor the needle, and with Springs e98 urging the jaw :memberszagainst the needle. The locking pin Hi2 maythen :be rotated so as to draw the slide further within the slide holder-and to rigidly secure the needle in its (desired position.

Since from the foregoing, the construction and advantages of this intravenous needle immobilizer are readily apparent, further description islbelieved to be unnecessary.

However since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoingspecification and accompanying drawings, it is not intended to liinit the invention to the precise embodiment of V intravenous needle holder shown and described,

abut :all' suitable modifications and equivalents may be resorted to which lie Within the scope of the appended claims.
